7 FIRST OPERATING
To complete the start-up of the boiler, the following opera-
tions are necessary, that should only be performed by an
authorized Service
B
:
- verification of the installation;
- slave board setting
- combustion analysis.
7 .1 Slave board setting
This operation that should only be performed by an author-
ized Technical Assistance Centre
B
.
Each slave unit that composes the system should be iden-
tifiable from the only master board, through an address that
is assigned properly configuring the switches J10 and J17,
on each slave battery. Each slave (one for each burner)
needs to be properly configured so that the Master board
shall detect their right sequence.
The slaves are divided into blocks of four slave each (every
Power Plus Box P INT-EXT
is a block) and the system can
handle up to 15 blocks.
Therefore, the address configuretion is done for each slave
using the following procedure, always remembering that a
block is equivalent to a unit:
- locate the block the slave is related to (ex. block n°1,
n°2, etc., till block n°15);
- locate the slave position inside each block (e.g. po-
sition1,2,3 or 4);
- supply each
Power Plus Box P INT-EXT
composing the
battery (see par.6.4.1).
b
Qualified personnel only may work on the electrical
system and in compliance to provisions of the law,
with particular attention to rules on safety.
As shown in Figure 24to set the address of the block you
should work on the switch located on the right (Jumper
J17) and for each slave (single burner) on the Left one
(Jumper J10).

Refer to the table to see the possible combinations of the
jumpers J10 that characterize the four slaves (n 1, 2, 3 and
4) of the same block.

The data have to be used regardless of the number of units
present: if, for example, have 6 blocks in the battery we will
consider combinations until the line corresponding to the
6th block, and not beyond.
In the following part is an example of configuration of a
battery with seven burner in cascade.
7 .1 .1 Example of configuretion of a battery
with 7 burner in cascade
In case two blocks are present in an installation having
a battery of seven burners (i.e. seven slaves): the first is
made of 4 burners and the second is made of 3. As a con-
sequence, two blocks need to be configured, respectively
with address 1 and 2 and with relative burners, to the first
block with address 1,2,3 and 4, and to the second block
with address 1,2 and 3 (see Figure 25).
